hw/input/hid.c Fix capslock hid code

When ever USB keyboard is used, e.g. '-usbdevice keyboard' pressing
caps lock key send 0x32 hid code, which is treated as backslash.
Instead it should be 0x39 code. This affects sending uppercase keys,
as they typed whith caps lock active.

While on x86 this can be workarounded by using ps/2 protocol. On
Power it is crusial as we don't have anything else than USB.

This is fixes guest automation tasts over vnc.
